Studies on Wax Secretion of Chinese White Wax Scale (Ericerus pela Chavannes)Ⅰ:The Comparison on Wax Secretion of Different Geographic Varieties

  • Received Date: 1997-02-15
  • It is reported in this paper that the wax secretion state of three geographic varieties of Chinese white wax scale.The research results have shown that Kunming variation has the longest wax secretion period and the largest wax secretion amount,Zhaotong variation has shorter period and less amount than Kunming variation,Jinkouhe variation has the shortest wax secretion period and the least wax secretion amount among the three varieties.There is a wax secretion peak in whole wax secretion period.Kunming variation peaks on the 50th day after the beginning of wax secretion, Zhaotong variation peaks on the 30th day,Jinkouhe variation peaks on the 20th day.The experimental results of esterase and peroxidase isozymes have demonstrated that there are some degree of differentiation among the three geographic varieties.There is small differentiation between Kunming and Zhaotong variations,but they differ obviously from Jinkouhe variation.

Abstract: It is reported in this paper that the wax secretion state of three geographic varieties of Chinese white wax scale.The research results have shown that Kunming variation has the longest wax secretion period and the largest wax secretion amount,Zhaotong variation has shorter period and less amount than Kunming variation,Jinkouhe variation has the shortest wax secretion period and the least wax secretion amount among the three varieties.There is a wax secretion peak in whole wax secretion period.Kunming variation peaks on the 50th day after the beginning of wax secretion, Zhaotong variation peaks on the 30th day,Jinkouhe variation peaks on the 20th day.The experimental results of esterase and peroxidase isozymes have demonstrated that there are some degree of differentiation among the three geographic varieties.There is small differentiation between Kunming and Zhaotong variations,but they differ obviously from Jinkouhe variation.
